Nolina brittoniana is fire-tolerant and is probably fire-dependant. It is restricted to central Florida in Marion, Lake, Orange, Hernando, Polk, Osceola, and Highlands counties. The plants are rare and listed as endangered by Florida and the U.S. Fish and Wildlife Service under the Federal Endangered Species Act.
